Curious claims are being made from various sources regarding the origin of the oil platform fire, explosion, and sinking. But even if the oil platform was deliberately destroyed, as some are claiming, the well itself should have had some type of inbuilt mechanism -- a blowout preventer -- to stop oil flow in case of a catastrophic disruption in continuity of the piping. [Update 1 May 2010: Apparently the blowout preventer at the site failed to operate. At this time no one knows why the blowout preventer failed. Certain automatic safety switches that were not included in the operation may have been able to trigger the blowout preventer.]
